This might be a very stupic question, but to be one the safe side, I'm still asking:

My current H1B will expire on Sep 15 2014, my employer just got it renewed with premium process, so the new H1B says valid from Sep 16 2014 to Sep 15 2017. I plan to travel to Canada and come back before Sep 15 2014, (I'm Canadian citizen). Which H1B package should I use ? The one expired on Sep 15 2014, right ? Many thanks

最好避免9/15之前出国旅行.如果一定要去,带上新的和旧的H-1B批准通知I-797.入境时要求边检官员盖入境图章有效期至201

You added a complication by traveling to Canada before 9/16/2014
